Is the starting substance in a chemical reaction

Reactants is the starting substance in a chemical reaction

Explanation:

Reactants are chemical substance that is consumed in a chemical reaction to produce a new substance known as product. The reactant is the starting substance of all chemical reaction. Without the reactant the product cannot be formed.

The reactants are usually located on the left hand side of a chemical equation while the product is located at the right hand side of a chemical equation.

A chemical equation between the reaction of an acid like HCl and a base like NaOH can be written as follow

HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)

The Hydrochloric acid and the sodium hydroxide is the reactants of the equation above. The salt, Sodium chloride and water is the product of the chemical reaction.

imma come back to you hold on

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
